Patented Dec. 20, 1932 UNITED STATES CHARLES N. ARNOLD, OF CHAUMONT, NEWYQRK snownLow Application filed February 10, 1932. SerialNo. 592,102.

This invention relates to a snowplow; It is primarily aimed to provide anovel constructionwhich is adapted to be pushed by a truck or the likeand which will not re-' quire special fastening in order to couple orarrange the same in operative relation with respect to the truck.

Another object is to provide a novel construction in which the dischargemember is positively operated and in front of which colter or dividingmeans for plowed snow is provided.

Still further an object is to provide a novel observation means notlikely to become blurred or affected by agitation of the snow.

The more specific objects and advantages will become apparent from aconsideration of the description following taken in connec tion withaccompanying drawing illustrating an operative embodiment.

In said drawing Figure 1 is a plan view showing the plow in connectionwith a truck,

Figure 2 is a side elevation of the parts of Figure 1,

Figure 3 is a longitudinal sectional view taken on the line 33 of Figure1,

Figure 4 is a front elevation of the plow, 30 and Figure 5 is a crosssectional view taken on the line 55 of Figure 2.

Referring specifically to the drawing, the plow comprises metallic orother body of suitable size constituting a plow and adapted to be pushedinto snow, the forward end of the body being arranged diagonally at 11.Such body adjacent the rear has a closed wall 12, side walls 13 and 14,a top 40 wall 15. and a bottom wall 16. Said bottom wall 16 inclinesupwardly and rearwardly and delivers snow into which the plow 10 ispushed, to a discharging fan at 17, the top wall having an enlargement18 to accon1- 45 modate operation of such fan and a discharge opening 19being provided in the walls 13 opposite the fan, a flange 20 beingprovided in the face of the discharge opening 19. Said fan a shaft 21suitably journaled in bearings 22 and 23 provided on the plow and fromwhich shaft arms 24 radiate, having blades 25 fastened thereto. V Theshaft 21 is driven in any suitable mannor. as by means of a motor 26located in a suitable housing 27 extending from the wall 12. Motor 26may be of any desired type, for instance, an internal combustion engine,and may have a transmission mechanism between the same and shaft 21' todrive the latter at v different speeds according tothe speed of advanceof the plowv 7 A longitudinally disposed observation tube is provided at28 and connected by brack ets 29 to the plow 10. The tube 28is preferabyclosed at the front by a transparent glass 30. It will be noted thatthe tube extends to the front of-the device forwardly of the zone ofplowing of the snow so that there will be little likelihood; of the.glass=* becoming clogged or vision through the tube'obscured.

It will also be noted that a plurality of vanes or colters 31 dependfrom the wall15 and are arranged-in the path of the 'snow throughtheplow. Such 'colters, or vanes serve to separate the snow to facilitateits discharge by the fan 21.: 7

It will also be noted'that wings 32 extend rearwardly beyond the wall'12 and that a truck 33 or other propelling body, is adapted to drivebetween the wings 32 and abut the wall 12, therebyforming a sufiicientconnection and as the truck is driven, to drive or push the plowforwardly. It will also be realized that the inner endof the observationtube 28will be located adjacent the drivers position of the truck.

Various "changes may be resorted to .PI'O- vided they fall within thespirit and scope of the invention.

Whatis claimed is V 1. A plow of the class described having a hollowbody adapted to be pushed into the snow, said body having a dischargeopei1ing,.

a fan arranged to be engaged by the snow and to discharge the samethrough the opening, 95 wings extending rearwardly from the body todefine a zone for engagement by a propelling vehicle, said body having awall at an angle to the wings adapted for abutment by the said vehicle.a

2. A plow of the class described having a hollow body adapted to bepushed into the snow, said body having a discharge opening, a fanarranged to be engaged by the snow and to discharge the same through theopening, wings extending rearwardly from the body to define a zone forengagement by a propelling vehicle, said body having a wall at an angleto the wings adapted for abutment by the said vehicle, a motor-to drivesaid fan, and a casing for said motor connected to the last mentionedwall and to one of said wings.

3. A plow of the class described having a hollow body adapted to bepushed into the snow, said body having a discharge opening, a fanarranged to be engaged by the snow and to discharge the same through theopening, wings extending rearwardly from the body to define a zone forengagement by a propelling vehicle, said body having a wall at an angleto the Wings adapted for abutment by the said vehicle, and anobservation tube supported on the body and extending forwardly of thezone of tanning. t

4. A plow of the class described having a hollow body adapted to bepushed into the snow, said body having a discharge opening, a fanarranged to be engaged by the snow and to discharge the same throughtheopening, wings extending rearwardly from the body to define a zone forengagement by a propelling vehicle, said body having a wall at an angleto the wings adapted for abutment by the said vehicle, and coltermeans0n ifzhe plow body in the path of the snow to the 5. A plow of the classdescribed having a hollow body adapted to be pushed into the snow, saidbody having a discharge opening, a fan arranged to be engaged by thesnow and to discharge the same through the opening, wings extendingrearwardly from the body to define a zone for engagement by a propellingvehicle, said body having a wall at an angle to the wings adapted forabutment by the said vehicle, an observationtube supported on the bodyand extending forwardly of the zone of fanning, and an inclined bottomfor said body extending upwardlytand rearwardly. a

In testimony whereof I aflix my signature.
